Europe's Semiconductor Crisis: Key Vulnerabilities and the EU's Chips Act 2.0 & Pax Silica Response

Heavy External Dependencies

The EU is deeply reliant on non-EU suppliers for advanced chips, chip design tools, semiconductor manufacturing equipment (SME), and upstream materials. The JRC reports map these dependencies across the full supply chain and note that listing a complete set of vulnerabilities is itself a challenge . Crucially, the value chain shows that nearly 80% of input suppliers and 63% of customers to EU companies are located outside the bloc .

No Advanced-Node Fabs on EU Soil

The EU has essentially no manufacturing capacity for leading-edge logic chips below 5nm nodes, leaving it fully dependent on Taiwan (TSMC), South Korea (Samsung), and the US. The European Court of Auditors found that the original Digital Decade target — producing 20% of global semiconductor value by 2030 — is "very unlikely" to be reached with current investment levels .

Taiwan Strait Concentration Risk

A disruption in the Taiwan Strait would cut off the majority of advanced chip supply globally, and the EU's end-user industries (automotive, industrial, medical devices) would be among the hardest hit. A Council document notes that "individual shocks like the Nexperia incident and attempts to economically coerce the EU" have already demonstrated system fragility .

Chinese Export Controls on Critical Materials

China dominates the supply of rare earths and certain critical minerals used in chip manufacturing and advanced packaging. The reports flag this as a growing coercive lever, with an EU-funded study by the EU Institute for Security Studies warning that the sector faces a "bleak future" partly due to Chinese export controls on minerals and magnets .

High Energy Prices and Scarce Private Capital

The EU suffers from higher industrial electricity costs compared to Asia and the US, while private capital for semiconductor fabrication — a capital-intensive, long-payback industry — has been scarce. Industry groups have called for coordinated EU-wide tax incentives, fast-track permitting, and affordable energy to close the investment gap .

Workforce and Innovation Pipeline Gaps

The ECA report highlights weaknesses in the "lab-to-fab" innovation pipeline, with insufficient translation of EU research into commercial production . The European Chips Skills Academy projects an average annual shortfall of around 10,800 skilled workers by 2030 across the value chain .

Policy Response 1: The Chips Act 2.0

The Commission proposed the Chips Act 2.0 on 27 May 2026 as part of a broader "tech sovereignty package," repealing and replacing the original 2023 Chips Act . Its main measures address the identified vulnerabilities directly:

• Manufacturing for advanced and mainstream nodes. The Act aims to support both cutting-edge (sub-5nm) and "mainstream" chip production where the EU holds competitive advantages .
• Sovereign and strategic projects. It establishes "Projects of Common European Interest" (IPCEI-like) vehicles for sovereign and advanced manufacturing, advanced chip design, and supply-chain resilience .
• Demand-boosting and market monitoring. For the first time, the EU will actively work to boost demand for chips made in Europe and improve monitoring to detect shortages earlier .
• Simplified regulatory framework. The Act aims to streamline state-aid rules, fast-track permitting with approvals within a maximum of 12 months, and reduce bureaucratic barriers .
• Pilot lines and R&D scale-up. The "Chips for Europe Initiative 2.0" supports five pilot lines covering sub-2nm logic, FD-SOI, power electronics, neuromorphic chips, integrated photonics, graphene, and 2D materials .
• Workforce and energy provisions. Accompanying measures include workforce training programmes and efforts to improve access to affordable energy for semiconductor fabs .

Policy Response 2: The Pax Silica Declaration

The European Commission signed the Pax Silica Declaration on behalf of the EU on 25 June 2026, joining a US-led strategic initiative focused on securing AI and semiconductor supply chains .

• A multilateral trust network. Pax Silica is a framework originally launched by the US State Department in December 2025. Signatories now include the US, Japan, South Korea, Singapore, the Netherlands, Germany, Greece, and the EU, coordinating on trusted supply chains for semiconductors, AI infrastructure, critical minerals, and data centres .
• Countering Chinese leverage. The initiative explicitly aims to reduce collective dependence on China for rare earths, critical minerals, and key processing steps, and to coordinate export controls on advanced chip technologies .
• Geopolitical hedge against Taiwan Strait disruption. By diversifying supply chains across a trusted bloc of allies, Pax Silica reduces the catastrophic single-point-of-failure risk posed by Taiwan's dominance in advanced logic manufacturing .
• Regulatory autonomy vs. alliance cohesion. There were weeks of internal EU debate before joining, with some member states and MEPs worried that Pax Silica could constrain the EU's regulatory autonomy (e.g., on AI rulemaking and technology transfer rules). The Commission ultimately decided the security benefits outweighed those concerns .

Complementary Measures

Beyond the two flagship initiatives, the Commission has taken additional steps:

• Crisis simulation. A full-scale simulation exercise on semiconductor supply chain disruptions was run in November 2025 to test coordinated crisis response .
• Alliance on Processors and Semiconductor Technologies. Industry and research organisations continue to be onboarded through this operational community for implementing Chips Act objectives .
• Implementation dialogue. A dedicated stakeholder dialogue process was launched in early 2026 to incorporate industry feedback into the Chips Act 2.0 revision .

Will It Be Enough?

The EU's diagnostic reports paint a picture of deep structural dependence on a small number of non-EU actors — with the Taiwan Strait concentration risk as the single most severe vulnerability. The policy response is a two-track strategy: internal capacity-building via the Chips Act 2.0 and external alliance-building via Pax Silica.

However, the European Court of Auditors' Special Report 12/2025 warns that even the combined efforts may fall short of the EU's 2030 ambition without urgent "reality-check" corrections and a significant scaling-up of investment . The EU semiconductor ecosystem is estimated to need €120 billion in public and private investments by 2035 to close the gap .
